A servo motor 14 is provided, and the output end of the servo motor 14 is transmission-connected with a rotating rod 23. The outer side of the rotating rod 23 is movably sleeved with a guide inclined plate 15 through a bearing. A plurality of grinding and crushing knives 18 are fixedly installed on the outer side of the rotating rod 23. A plurality of spiral blades 19 are fixedly installed on the outer side of the bottom end of the rotating rod 23. A guide cone 20 is fixedly installed at the bottom of the inner cavity of the filter cylinder 17. A plurality of guide holes 21 are opened inside the guide cone 20. A support shaft seat 22 is fixedly installed on the top of the middle part of the guide cone 20. A guide cover 13 is fixedly installed on the middle part of the bottom of the base 2. The bottom end of the guide cover 13 is connected with a bellows 5. A manual valve 6 is arranged inside the bellows 5. Both sides of the bottom end of the tank body 1 are connected with a discharge pipe 4. A handle 7 is fixedly installed on the outer side of the tank body 1.

[0020] The working principle of the above technical solution is as follows: when in use, the user moves the device to the working position through the handle 7 and the universal wheel 3, and then starts the vacuum suction pump 9. The vacuum suction pump 9 draws out the airflow inside the tank body 1 through the suction pipe 8, forming a negative pressure inside the tank body 1. At this time, the airflow enters through the hose 11 and the suction head 12, and enters the inner side of the filter cylinder 17 through the diversion of the guide pipe 24. Before this, the operator injects water into the tank body 1 by opening the filling pipe 10. When the airflow carries paper scraps into the filter cylinder 17, the airflow bypasses the guide inclined plate 15 and is discharged through the filter column 16 and the suction pipe 8, and the paper scraps are discharged through the air filter. Due to the inertia of the flow and the diversion interception of the guide inclined plate 15, the paper scraps are intercepted when in contact with the water flow inside the tank body 1, and are accumulated on the inner side of the filter cylinder 17. When a certain amount of paper scraps are collected, the servo motor 14 is started to drive the rotating rod 23 to rotate, and the grinding and crushing knife 18 and the spiral blade 19 are driven to rotate by the rotating rod 23 to crush the paper scraps on the inner side of the filter cylinder 17, and the fine paper pulp is filtered by the filter cylinder 17 and overflows to the outer side of the filter cylinder 17, and then the manual valve 6 and the discharge pipe 4 are opened respectively to collect the paper pulp for recycling. This solution facilitates the cleaning of the operating personnel, increases the efficiency of recycling, and facilitates the operation.

[0021] In another embodiment, Figure 1-Figure 3As shown, the air intake pipe 8 is fixedly passed through the tank body 1 and extends to the interior of the tank body 1 , and the filter column 16 is in an inverted L shape and extends to the interior of the filter cylinder 17 .

[0022] The suction pipe 8 draws out the air flow inside the tank body 1, and the filter column 16 allows paper scraps to enter through the suction pipe 8, thereby limiting the position of the paper scraps and reducing blockage. Through the set filter cylinder 17, during the paper scrap crushing operation, as the rotating crushing and stirring proceeds, pulps of different particle sizes will be automatically separated inside and outside the filter cylinder 17, thereby realizing the recycling of different paper scraps and pulps, facilitating the separation of coarse fiber pulp and fine fiber pulp, thereby respectively extracting the fine fiber pulp and the coarse fiber pulp for recycling, thereby improving the efficiency of recycling and facilitating the coordination of subsequent different recovery powers.

[0023] In another embodiment, Figure 1-Figure 3 As shown, the bottom end of the filling pipe 10 is fixedly passed through the tank body 1 and extends to the inside of the filter cylinder 17, and a valve is arranged inside the discharge pipe 4.

[0024] A sealing cap is provided at the top of the filling pipe 10. After opening, a proper amount of water is injected into the tank body 1 through the filling pipe 10. After the operation is completed, the fine pulp is discharged by opening the discharge pipe 4, which is convenient for separate extraction.

[0025] In another embodiment, Figure 3 As shown, both ends of the guide plate 15 are fixedly mounted on the inner wall of the filter cylinder 17 , one side of the top end of the guide plate 15 corresponds to the position of the guide tube 24 , and the other side of the bottom end of the guide plate 15 corresponds to the position of the filter column 16 .

[0026] The inclination of the guide ramp 15 facilitates the separation of the passing paper scraps and the airflow. When the water overflows the guide pipe 24, the pulp will directly enter the water. The guide ramp 15 guides the paper scraps, and as the paper scraps move, they enter the water with inertia, thereby increasing the separation effect of the paper scraps and the airflow.

[0027] In another embodiment, Figure 3 As shown, the grinding and crushing knives 18 are evenly distributed inside the filter cylinder 17 in a spiral spiral shape, and the spiral blades 19 are evenly distributed on the outer side of the rotating rod 23 in a circumferential shape.

[0028] The spiral distribution of the grinding and crushing knife 18 is convenient for evenly crushing the paper scraps, and the disturbed water flow of the spiral blade 19 is convenient for turning over the pulp water, so that the pulp is evenly crushed and the grinding efficiency is improved.

[0029] In another embodiment, Figure 3 and Figure 4As shown, the support shaft seat 22 is movably sleeved at the bottom of the rotating rod 23, and the guide hole 21 passes through the guide cone 20, the tank body 1 and the base 2 and is connected to the inner side of the guide cover 13. The guide holes 21 are evenly distributed in a circle inside the tank body 1, the base 2 and the guide cone 20.

[0030] The support shaft seat 22 provides bottom support for the rotating rod 23, so that the rotating rod 23 can rotate stably, and the guide hole 21 guides the liquid guided by the guide cone 20 to be discharged through the guide cover 13 and the bellows 5, so as to guide the pulp and guide it separately.

[0031] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
